Figure 1: Best track positions for Tropical Depression Three-E, 27-29 June 2002.
Tropical Depression Three-E developed from a well-defined tropical wave that emerged off the west coast of Africa on 12 June. It moved westward and crossed the Lesser Antilles on the 17th with a marked cyclonic wind shift. After crossing Central America, the wave continued westward and the shower activity increased considerably. By 23 June, there was a distinct disturbance with multiple low-level centers as indicated by data from QuikSCAT. One center became dominant and it is estimated that a tropical depression formed at 1200 UTC 27 June about 970 n mi southwest of the southern tip of Baja California, Mexico. The depression changed little in organization during the following 24 to 36 hours . Rapid weakening occurred on the 29th as strong shear separated the low-level center from the thunderstorm activity. A swirl of low clouds continued moving westward for a few more days. The best track positions and intensities are listed in Table 1 and Figure 1 shows a plot of the depression's track.
